A federal judge today set June 28 for sentencing for former political insider Stuart Levine, a key government witness at two trials over corruption stemming from the administration of former Gov. Rod Blagojevich.

U.S. District Judge Amy St. told prosecutors she wants to hear extensive details about how Levine earned a deal with prosecutors to serve a sharply reduced prison sentence.

Levine pleaded guilty nearly six years ago to attempted kickback schemes involving his positions on the state teacher pension board and the state hospital construction board.

According to Levine’s 58-page plea agreement– which extensively detailed his illegal scheming – prosecutors agreed to recommend a 5 1/2-year sentence in exchange for his cooperation. Under federal sentencing guidelines, he faced up to life in prison.

As she scheduled the sentencing today, St. Eve told prosecutors that she expected to hear a “lengthy recitation of Levine’s cooperation.”

Levine testified against former Blagojevich fundraiser Antoin “Tony” Rezko, who is now in federal prison, and was the star witness against Springfield power broker, William Cellini, who is awaiting sentencing.

During his testimony at Cellini’s trial, Levine described in detail the million-dollar bribes he tried to orchestrate on victims ranging from close friends to the Chicago Board of Education. He also told of his extensive drug use and cocaine parties he attended at the former Purple Hotel in Lincolnwood.
